Hardware Notes : This game uses 3 x PC080SN for generating tilemaps. They must be mapped somehow to a single memory block and set of scroll registers.
There is an additional text tilemap on top of this, to allow for both background planes scrolling. This need is presumably what led to the TC0100SCN tilemap chip, debuted in Ninja Warriors (c) 1987. (The TC0100SCN includes a separate text layer.)

Flyers : Normal FlyerNotes : The game boards produce two separate video outputs that are sent to two different screens housed in the cabinet. A half-silvered mirror is used to mix the images from the two screens in such a way as to produce a pseudo-3D effect. Backgrounds and enemies on the ground are displayed in the lower screen, while player ship and enemies in the air are displayed in the upper screen. These appear to be at different depths to the eyes of the player, thus giving the illusion of sprites in the air floating above the ground.To further enhance the effect, the cabinet also has two speakers. The sound of enemies on the ground is heard from the bottom speaker, while the sound of enemies in the air is heard from the top speaker.
